[Qemu-devel] [PATCH 2/2] ARM: wire up the softfloat flush_input_to_zero flag

2011-01-03 Thread Peter Maydell
Wire up the new softfloat support for flushing input denormals to zero on ARM. The FPSCR FZ bit enables flush-to-zero for both inputs and outputs, but the reporting of when inputs are flushed to zero is via a separate IDC bit rather than the UFC (underflow) bit used when output denormals are flushe
